Question

I am very new to C# coding, so this may be very simple. In my Site.Master.cs, I have the following code:

GetLoggedInUserProperties();
lblLoginUser.Text = string.Format("Welcome {0}", Session[SessionVars.UserName]);

In a class file, I have put the following in a Public Class:

void GetLoggedInUserProperties()
    {
        string sLoginId = Program.ExtractUserName(HttpContext.Current.Request.ServerVariables["LOGON_USER"]);
        HttpContext.Current.Session[SessionVars.LoginId] = sLoginId;

        VerifyInAD(sLoginId);
    }

There are no errors in the class file, but my Site.Master.cs cannot find the code in the class file.

I am sure there is a better way to do this, so feel free to let me know. Also, the lblLoginUser does not seem to work either. It has the same error. I have tried recreating the label and deleting the designer file (which never came back). Not sure if this is related or not.

Thank you.

Answer 1

You need to make your methods public or protected to be visible from the markup. So if you want to reference GetLoggedInUserProperties() from the markup, you'll need to change your method declaration to something like this.

protected void GetLoggedInUserProperties()
{
}

Answer 2

Make your method public

Here your class

public class ClassName
 {
       public void GetLoggedInUserProperties()
       {

       }

 }

public MainWindow()
{
                InitializeComponent();
                ClassName instance = new ClassName();
                instance.GetLoggedInUserProperties();

}

Or make your class static and call your method :

  public static class ClassName
   {
       public static void GetLoggedInUserProperties()
       {

       }

    }



 public MainWindow()
  {
                InitializeComponent();
                ClassName.GetLoggedInUserProperties();

   }
